RAILROAD-TIE.

SPECIFICATION forming part-of Letters Patent No. 255,392, dated March 21, 1882.

Application filed July 14, 1881. (No model.)

To all whom it may concern Be it known that I, PHILIP PENDLETON,

Bath, in the county of Morgan and State of WestVirginia, have invented certain Improvements in Railroad-Ties; and I hereby declare the following to be a full, clear, and exact account thereof, reference beinghad to the accompanying drawings, making part of this specification, in which- Figure l is a perspective View of the tie and sections of rail. Fig. 2 is a longitudinal sectional view. Figs. 3, 4, 5, and 6 are details to be referred to.

The object of my invent-ion is to provide a I 5 railroad-tie which will have great endurance and comparatively a low cost.

My invention consists of a certain combination and arrangement of devices, as hereinafter more fully described and claimed.

In order that those skilled in the art may make and use my invention, I will proceed to describe the manner in which 1 have carried it out.

In the said drawings, Ais the tie-bar, made 2 5 of forged, rolled, or cast metal, and provided with flaring ends. On each end of the tie-bar are secured by means of broad dovetail grooves a boxes B B, having their sides contiguous to the outerends of the tie-bar curved, as seen at o 1), and formed into hook-shaped socketsd I], to receive one edge of the flanges e of the rails D. Within the boxes B B are placed blocks E,

of some non-rigid, yielding, or semi-elastic material, preferably wood, to form seats, upon 5 whichrestthe bottomsot'theflangesoftherails. A binding-plate,P, lies upon each block E, and has its edge 1) resting on the flange e of rail D. At each end of the tie a bolt, 0, passes through tie-bar, box B, block E, and binding-plate P,

and secures them all together, and through the, medium of plate P binds the rail down on block E.

It is evident that the blocks E may be made of any material which sufficiently lacks rigidity to take up, or partially take up, the jar on the rails when trains are passing without departing from the spirit of my invention. The blocks, being easily removable,when worn, can

be easily replaced without removing the rail,

except from the particular tie containing the block to be changed.

For convenience I may prefer to slot the ends of the blocks, as seen at 01, instead of boring them, to receive the bolt 0. This construction enables me to remove the blocks and replace them without removing the binding-plates by simply loosening up the nutp and sliding the block into the box from the outside of the rails.

I find it desirable to contract the width of the tie-bar A toward the center, because it is an economy of metal, and no material width of the bar is necessary at the center to withstand any tensile strain. that may be put upon it; but the same can be made of any size or 1 shape or weight deemed necessary to secure the requisite strength.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination and arrangement of the tiebar A, removable boxes B 13, blocks E, binding-plates P P, bolts 0, and rails D, substantially as and for the purpose set forth.

PHILIP PENDLETON.
